Abstract (en)
[origin: WO2019219724A1] The invention relates to a method for automatically regulating the size of a nozzle discharge slot of a nozzle assembly, wherein the nozzle assembly comprises a first and a second nozzle lip and a nozzle discharge slot arranged between the nozzle lips for setting in a controlled manner a thickness profile of a conveyable melt. A plurality of adjusting elements, in particular a plurality of adjusting pins, coupled to respective thermoelements, is arranged on the first nozzle lip, the thermoelements being controllable by the controller in such a way that the slot can be adjusted by the action of a mechanical force applied to the first nozzle lip by the corresponding adjusting element, as a result of the expansion or contraction of the thermoelements. When the nozzle assembly is first put into operation for conveying the melt, the adjusting elements are set once only without play as a starting setting before a subsequent control. The invention further relates to a control and/or regulation system.
